means being provided whereby when the re-. ceptacle is manually rotatedandthen re-,

leased, said receptacle will be rotated in an opposite direction,thereby causing the receptacle and the dashers to oscillate in oppositedirections.

A preferred and practical embodiment of the invention is shown in theaccompanying drawings, wherein Figure 1 is a central vertical sectionalview of the improved churn. Fig. 2 is a horizontal sectional View. Fig.3 is a detail perspective view of the support for the dash:

ers. Fig. 4 is a detail perspective view of the sleeve that carries thedasher support. Fig. 5 is a detail perspective view of one of thedashers. Fig. 6 is a detail perspective view of the bearing for theoperating shaft.

The improved churn comprises a stand including a central verticallyarranged bearing 7 from the base of which downwardly inclined arms 8radiate and terminate in pendent end flanges 9 that overlap and arefastened to the upper ends of the supporting legs 10 that rest on thefloor.

A shaft 11 is journaled in bearing 7 and projects through a centralopening 12 in the bottom of a churning receptacle 13. A sleeve 14 iscentrally disposed in receptacle 13 over opening 12 and has a baseflange 15 that is fastened to the bottom of said receptacle. Shaft 11projects above the upper end of sleeve 14 and a short sleeve 16 isrotatabl fitted over the upper end of sleeve 14 an has a reduced upperend 17 that is keyed or otherwise rigidly fastened to the upper end ofsaid shaft. The lower external portion of sleeve 16 is provided withregularly spaced longitudinally extending ribs 18 having laterallyprojecting flanges 19 at their lower ends. A dasher supporting sleeve 20is fitted over sleeve 16 and is provided with regularly spaced internallongitudinal slots 21 with which ribs 18 interlock. Sleeve 20 seats onflanges 19 and has fiat arms 22 radiating therefrom upon which thehorizontal dasher bars 23 are fastened. Bars 23 have the spaced blades24 depending therefrom, said blades being connected by the bars 25. Theouter end portions of bars 23 are connected by the brace rods 23*.

A beveled gear 26 is fast on the bottom of receptacle 13 and looselysurrounds shaft 11, said gear being in mesh with a beveled gear 27 thatis journaled in a boss 28 that projects laterally from a sleeve129 thatis held on shaft 11, by a bracket 29 projecting from bearing 7. Shaft 11has a beveled gear 30 fast thereon that is in mesh with gear 27. Thedescribed gearing obviously causes shaft 11 and receptacle 13 to rotatein opposite directions. Arms 8 of the supporting stand have upstandingeyes 31 at their outer end and said eyes have spring connections 32 witheyes 33 depending from the bottom of receptacle 13. A flanged cover 34is provided for receptacle l3 and carries hooks 35 that engageeyes 36 tolock said cover to said receptacle. A hand grip 37 is provided for thecover 34. Receptacle 13 has a base drain opening that is normally sealedby a plug 38. Receptacle 13 is also provided with one or more handgrips39.

In operation, the receptacle 13 is manuually oscillated by grasping thehandgrip 39, such movement placing the springs 32 under tension so thatwhen the manual pressure is removed, or reduced, the spring will causethe receptacle to assume its original position. The oscillatingmovements of receptacle 13, through the gears 26, 27 and 30 oscillatethe dashers in directions opposite to the movements of the saidreceptacle. As will be clear, the spring connections 32 facilitate theoscillations of the receptacle 13.

From the foregoing description it will be clear that the dashers can bereadily removed' from sleeve 16;.the spring 32 disconnected from theeyes 31 and 33 and the sleeve 16 disconnected from the shaft 11 so thatthe receptacle 13 can be readily lifted from the shaft 11. Thisconstruct-ion obviously facilitates cleaning, as well as making repairsand substitution of parts.

' vWhat I claim as my invention is 1. A churn comprising a support, ashaft journaled therein, a receptacle provided with a central bottomopening through which said shaft projects, a sleeve carried by andlocated within said receptacle and surrounding said shaft, a sleevecarried by said shaft and surrounding the upper portion of said firstmentioned sleeve, said shaft sleeve being provided with externallongitudinal ribs carrying laterally projecting flanges, a dashersupporting sleeve seated on said flanges and provided with internalgrooves with which said ribs interlock, arms radiating from saidsupporting sleeve, dashers carried by said arms, means operated by arotary movement of the receptacle for rotating the shaft in an oppositedirection, and yieldable means opposing rotary movement of saidreceptacle.

2. A churn comprising a support, a shaft rotatably mounted in saidsupport, a tub provided with a central opening through which said shaftpasses, a sleeve leading from said opening and surrounding the innerportion of said shaft, the inner end of said shaft extending above saidsleeve, a second sleeve secured to the inner end of said shaft andsurrounding said first-mentioned sleeve, dashers connected with saidlast-mentioned sleeve, means for rotating said tub, and shaft, andsprings connecting said tub with said support.

3. A churn comprising a standard, a tub, a shaft mounted in saidstandard. and passing into said tub, a sleeve surrounding said shaft, asecond sleeve connected with said shaft and surrounding said firstmentioned sleeve, a collar removably mounted upon said second-mentionedsleeve, and dashers connected with said collar.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.
